You need this for a 160mm rear rotor

I know there are a lot of disc configurations but I was annoyed to find that the "160mm f/r" disc brake set I bought included an adapter that worked for 160mm front rotors but 140mm rotors in the rear.

Cons: that I have to buy this

Includes Mounting Bolts!

I ordered the 74mm post mount to 185mm rotor mounting bracket and, unlike the description, it comes with the longer bolts. A nice surprise! The adaptor installed without issues and works fine. I was using one of the cheaper adaptors that just had two longer spacers to get the caliper out to clear the rotor and was getting a lot of brake chatter. This proper bracket eliminated the chatter, by providing a stiffer mount. Problem solved!

Pros: Stiff, Easy to Install, Comes with bolts

Cons: None

The adapter does exactly what you'd want it to do. Matches up well to the avid brakes (almost like they're designed together... ;-)

Pros: like that I can pick up just the adapter-- got enough bolts in the parts bin to put everything together.

When used with a Tektro caliper, the pads were not aligned with the disc exactly right. I can't speak to an Avid caliper. The screw holes did not quite match up to my caliper either and the calipers were hard to adjust. Probably due to the different mfgs, but ppl should still be aware

It comes with longer screws!!!!!

I needed an adapter to put a 185mm rotor on the front fork.

I thought I was going to be on the hook for longer screws too.

Fortunately, the adapter came with longer screws with threadlocker.

Pros: Puts the brake in the right place for a larger rotor
Came with the necessary longer screws
Screws had threadlocker

Really bolts onto tabs

Reviewing an adapter is a difficult endeavor to manage well, as most of the time the consumer puts them on the bike and then forgets about them.

This is what I did, so I'd say they work just like you would think they would.

Pros: Didn't strip, didn't break. And I have lots of them on several bikes.

Cons: none.
